About BRFSS and ICBRFS
The Behavioral Risk Factor Surveillance System (BRFSS) is a state-based program that gathers information on risk factors among Illinois adults 18 years of age and older through monthly telephone surveys. Established in 1984 as a collaboration between the U.S. Centers for Disease Control and Prevention (CDC) and state health departments, the BRFSS has grown to be the primary source of information on behaviors and conditions related to the leading causes of death for adults in the general population.

The Illinois County Behavioral Risk Factor Surveys (ICBRFS) are conducted for individual counties employing the same procedures and questions as the BRFSS.

For more information about the BRFSS program at CDC, visit that agency's website at www.cdc.gov/brfss.
